As the leading James Hardie contractor in Whatcom County, Siding Vault has compiled these maintenance tips based on decades of combined experience. Follow them, and your siding will reward you with lasting beauty and protection.

The Simple Annual Wash That Makes a Difference

Whatcom County’s damp climate means that dirt, pollen, and mildew will eventually accumulate on any exterior surface. The good news is that cleaning your James Hardie siding is straightforward and doesn’t require harsh chemicals or expensive equipment. Once a year, ideally in late spring after the worst of the rain has passed, give your home a gentle wash. Use a garden hose with a spray nozzle, a soft-bristled brush or sponge, and a simple solution of water and mild dish soap. Work from the bottom up to avoid streaks, and rinse thoroughly. That’s it. Avoid pressure washers, which can force water behind the siding and damage the factory finish. Also avoid bleach-based cleaners, which can discolor the ColorPlus finish over time. A gentle annual wash removes mildew spores before they become established and keeps your home looking its best.

Inspecting Caulking and Sealants Around Openings

Caulking around windows, doors, and other openings is your siding’s first line of defense against water intrusion. Over time, even the best caulking can shrink, crack, or pull away from surfaces. Siding Vault recommends inspecting all caulked areas once a year, ideally during a dry spell. Look for gaps, cracks, or areas where the caulking has separated from the siding or trim. Pay special attention to the tops of windows and doors, where water tends to collect. If you find compromised caulking, remove the old material and replace it with a high-quality, paintable exterior caulk rated for fiber cement. This simple task takes an afternoon but prevents water from seeping behind your siding and causing hidden damage. If you’re uncomfortable working on a ladder or unsure what caulk to use, Siding Vault offers inspection and maintenance services to handle this for you.

Keeping Gutters and Downspouts Clear

It might seem unrelated, but your gutter system directly affects your siding’s health. Clogged gutters overflow, sending water cascading down your siding rather than away from your home. Over time, this constant drenching can overwhelm even the best weather barrier. Siding Vault recommends cleaning your gutters at least twice a year—in late spring after tree pollen season and again in late fall after the leaves have dropped. Ensure downspouts extend at least four feet from your foundation, and consider adding splash blocks or extenders if water pools near your walls. Also check that gutters aren’t pulling away from the fascia, which can allow water to run behind them and down your siding. These simple gutter maintenance tasks protect your entire exterior, not just your siding.

Trimming Landscaping Away from Your Home

Whatcom County homeowners love their landscaping, but overgrown bushes and trees can damage siding. Branches scraping against walls can scratch the ColorPlus finish, creating entry points for moisture. Dense shrubs pressed against siding trap moisture and reduce airflow, promoting mildew growth. Siding Vault advises keeping all vegetation at least six inches away from your siding. Trim back tree branches that overhang your roof or touch your walls. Prune shrubs and bushes so they don’t press against the siding, especially on the north side of your home where moisture lingers. This not only protects your siding but also allows you to inspect the lower portions of your walls for any issues. A little landscaping maintenance goes a long way toward preserving your siding’s appearance and performance.

Watching for Early Warning Signs

The best maintenance is catching small problems before they become big ones. Siding Vault encourages homeowners to walk around their home a few times a year, looking for early warning signs. Check for any panels that look loose or feel spongy when pressed. Look for gaps that have opened up between panels or between siding and trim. Note any areas where the ColorPlus finish appears faded, chipped, or peeling. Watch for mold or mildew growth that doesn’t wash away with gentle cleaning. Pay attention to interior signs too—musty smells, peeling interior paint, or soft spots near exterior walls can indicate hidden moisture issues. If you spot any of these warning signs, call Siding Vault promptly. Small repairs are almost always less expensive than major replacements, and catching issues early protects your home’s structure.
